Formaldehyde is particularly troublesome for those with chemical sensitivities, which may explain why you’re still suffering from rashes or eczema even after switching to less-toxic laundry soap and ditching fragranced dryer sheets.

Reduce your formaldehyde exposure:

1. Wash all clothes and linens BEFORE wearing or using—gets rid of about 60 per cent of the stuff
2. Avoid products labelled “wrinkle-free”, “iron-free”, “permanent-press” or “stain-resistant”
3. Perform a “sniff test”—if it smells chemical-y, don’t buy it, or return it
4. Choose organic cottons
